report from our chief science correspondent, robert bazell. >> reporter: for the first time ever, an experimental drug is showing great promise of slowing the alzheimer's disease. >> this is the first time we are seeing a slowing of the cognitive decline in patients with alzheimer's disease in this type of drug treatment. >> reporter: at first, the experiment experimental drug seemed to fail as has every experimental drug to date. but when the manufacturer looked at it more closely, it found those with more mild disease had a less memory loss than those with the placebo, the 71-year-old retired expert still functions well. >> there are things that take a lot longer than they used to because i keep forgetting the order in which things have to be done. >> reporter: the results presented today combined studies with a total of 2,000 patients in the last two months. most scientists say it wouldn't be enough to reach the fda approval. but further studies show that it could help people with early alzheimer's disease. the drug is certainly not the cure that everybody wants, but for al kr

, especially boys. a report from our chief science correspondent, robert bazell. >> reporter: jenna, like many moms, worries about producting her young kids from chemical contamination. especially the effects of the the chemical, bpa, found in plastics. >> i'm avoiding plastic in general. we try to drink out of glass. all of our water bottles, we take away with us, are reuseable. they're glass or metal. >> reporter: a new study suggests that moms may be passing along effects of bpa to their kids. in a study of 500 pregnant women, those with the highest levels of bpa have lower thyroid levels. and so did their infant sons. why only boys? scientists aren't sure. but they see the same thing in animal studies. thyroid hormones help control many systems in the body and can affect childhood development. >> if bpa is affecting the levels during pregnancy, this could be affecting the learning, memory and behavior of children later in life. >> reporter: bpa is part of many widely used plastic products. including can liners in certain bottles. most americans have trace amounts in their body.

their shots may have been contaminated. a report from our chief science correspondent robert bazell. >> reporter: about a million people receive steroid shots in the spine for back pain every year. several hundred patients are now receiving phone calls like this one -- >> this is cindy checking on our patients that had epidural steroid injections. need to know if everything's okay. >> reporter: health officials are now investigating 26 cases of severe meningitis in five states including four deaths. officials are trying to track down hundreds of other people in 23 states who got the injections and might be at risk. nbc news has learned health officials believe the outbreak originated at the new england compounding center near boston. the company is recalling hundreds of doses of a steroid compound it made for those lumbar injections believed to be contaminated with a fungus. >> one of the striking early features of this outbreak -- remember, we're still gathering data -- is that many of these patients are certainly middle-aged, they have back problems, but they're otherwise pretty h
